OHA - how does it work?

Construction of OHA X

OHA X is an advanced a system consisting of radiant belts with a Premix type gas burner and an additional condensing heat exchanger, using flue gas recirculation and recuperation.

The device allows flexible configuration of pipe shape and routing. External installation eliminates the need for gas sensors within and reduces the number of roof penetrations. The whole is managed by a smart control with LCD display and mobile app.

OHA X - benefits

Why is the OHA X the ideal choice for your project?

Significant cost savings

Thanks to recuperation and exhaust gas recirculation, OHA X saves nearly 20% in annual heating costs compared to standard radiant belt systems, which translates into real financial benefits.

High energy efficiency

105% efficiency level means that the system recovers more energyi, than traditional solutions, minimising losses and ensuring optimum use of fuel.

Reduction of CO2 emissions

Reduction in CO2 emissions by 17% makes the OHA X an environmentally friendly choice, supporting green building certifications such as BREEAM.

A complete HVAC solution

In addition to heating, OHA X delivers up to 4000 m³/h of heated fresh air, while ensuring efficient ventilation with heat recovery.

Intelligent and flexible control

The system allows management of up to 16 independent heating zones and scheduling programming, making it possible to precise adjustment of the temperature to the needs of the facility.
